Hexxit crashing after taking items out of a chest or clicking the chest GUI?

[Theriq]

I've been playing Hexxit for a couple hours now. I started yesterday, and everything worked fine. I had been play on it for a while. I had a couple of crashes then, but they weren't reoccurring. Now, about half an hour ago, I was playing on it and I opened a chest. I proceeded to put the items from the chest into my inventory, but when I clicked anywhere in the chest, Minecraft froze for a couple of seconds and then crashed. This has happened every time I opened a chest. I don't know what is wrong. I will post the error report if it is needed. Thanks in advance.

This happens on servers and single player worlds.
